I worked at a startup where I was largely left alone to get my work done, and things went along pretty well until the founder decided that I needed a manager and put me under the management of a loud, brash guy who did a lot of posturing and played a lot of power games but didn't seem to do much in the way of managing anybody. My work was unrelated to his area of expertise so fortunately we had very little to do with one another, but periodically he would come by to "check in," which generally consisted of standing outside my cubicle and insulting me and laughing at his own wit.

Our funding situation was touch-and-go, so it didn't surprise me too much when I got a call from him one day when I was working off-site. He said "I'm really sorry to have to tell you this, but our funding fell through and they're shutting us down. You can come in tomorrow and pack up your stuff." I reeled for a minute, asking the usual "How did this happen?" questions, and eventually he started laughing and shouted "April fools!" It was, in fact, the first day of April. Without thinking, I said "You're a dick," which only made him laugh harder.

A couple weeks later there was a round of layoffs, and he was replaced by a really nice guy who knew exactly what he was doing and was a great manager. A couple weeks after that, our funding fell through and they shut the company down.

A new district director was transfered in. All managers were warned that she would be insulted if anyone more than two pay grades lower than she tried to talk to her. As she stayed in her office and spoke to very few people, this did not present a problem.

Then came the day the headquarters executives would come to town. She determined that the most important thing done by her staff was the recruitment of minorities and handicapped people to entry level positions. She would put on a meeting for all employees at a hall to display the new employees to the hq execs.

Fate can be cruel. The managers warned all the minority and handicapped employees not to speak to the director under any circumstances. They were all quite a bit lower paid than the director and any attempt at conversation would be dealt with harshly.

The day and time of the presentation came and the employees filed into the hall. The hq execs, too, sat for the presentation. The director hurried to the meeting and excused herself from the rest of her staff and went to the ladies' room. Her staff went ahead and checked the stage. All the new employees were dutifully sitting at the curtain, so the director's staff sat down in the front rows.

The director entered from the center stage curtain. She walked to the podium and started her speech. The newly hired looked at each other. At first they seemed shocked, then confused as to what to do. Finally, they did as instructed, "Don't talk to the director."

The director finished her speech to polite applause. She turned around and walked back to the curtain. Her dress had been tucked into her pantyhose, revealing more of the director than anyone want to know.

...not exactly a corporation, but...
I worked for a small office furniture installation company for several years. Each year at Christmas, the owner would give us each a generous bonus. On the last year I worked with this company, Christmas crept closer and closer with no bonuses having been given out and no word of whether or not they were coming. The day before Christmas, the owner, who had recently returned from a long weekend in Las Vegas, announced to the company that no bonuses would be given out as it had been a "tough year for us". Some of my co-workers were crushed. Many of them had kids, for whom these bonuses were used to provide a nice Christmas. We're talking about some very blue-collar guys. When we returned to work after the holiday, we were greeted with the site of where our bonuses had really gone. The owner had parked his brand-new, top-of-the-line, 25 foot power boat in the warehouse. He, needless to say, was beeming ear to ear with enthusiasm. The productivity of the installation crews dropped off the charts. I have to say that I should thank him. That one act convinced me to go back to school and earn my degree. He closed the business 2 years later.

I've been working for my company for 3 years. We recently underwent a "restructure", which as far as most of us are concerned means an excuse to dump staff.

As part of this restructure, a lot of admin jobs came up, including my own. Now I like to think I'd done pretty darn well at my job, and it requires a little more technical knowledge than a regular admin job, due to it involving asbestos knowledge.

But still, I had to apply for my own job, along with many other admin staff. I was informed that my interview would involve a manager and a HR representative. When I went to the interview, I found that it actually consisted of *six* managers. This threw me straight away, and I was a bit nervous throughout the interview, but felt confident that since I knew so much about the job, I'd be fine.

I was informed less than a week later that I hadn't got my own job, and what was more I had to train the clueless girl that did get it how to do my job! Nice going...

My most embarrasing day at the job was when I crashed into the clear glass doors of my office, while I was holding my mocha. Plus it was my birthday, that day, and I was wearing all white.
Every single person in the office laughed. Even though I was the boss of everybody there.
On my next birthday, just when I got to the office; one of the employees came up to me, holding a mocha, and spilled it on my shirt.
Suddenly all the employees jumped out from their cubicles and yelled, “HAPPY BROWN SHIRT DAY!!!”
Every single person was wearing brown stained shirts.
Now they do this every year, and I gave them all promotions.
